MACHI NE FOR SCOURING CLOTH.

SPECIFICATION forming part of Letters Patent No. 550,276, dated November 26, 1895.

Application filed November 7, 1894. Serial No. 528,137. (No model.)

To aZZ whom it may concern:

Be it known that I, MATTHEW H. KoHL- RAUSOH, a citizen of the United States, residing at Billerica, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Machines for Securing Cloth, of which the following is a specification.

My invention relates to machines for scouring cloth; and it consists in the devices hereinafter described and claimed, the object of said invention being to guide the cloth properly to the squeeze-rolls and to change the folds of the cloth in such a manner as to bring different surfaces of the cloth in contact with said rolls at each passage of the cloth between said rolls. I

In the accompanying drawings, on two sheets, Figure 1 is a right end elevation of a scouring-machine containing my improvement; Fig. 2, a front elevation of the same; Fig. 3, a plan of the same; Fig. 4, a left side elevation of the first and second guides and their supporting-plate and the adjacent part of a tank to which said plate is secured; Fig. 5, a front elevation of some of the second or spiral guides and means of supporting and adjusting them, showing also a vertical section on the line 5 5 in Fig. 4 of the tank and supporting-plate; Fig. 6, a front elevation of the first or finger guides and the supportingplate and adj listing-screw and a vertical section of the supporting-plate and part of the tank; Fig. 7, an isometric perspective view of a single spiral guide detached.

The tank A, squeeze-rolls B B, submergingrolls 0 O, and carrier-roll D are of any usual construction, but preferably as shown in United States Patent No. 493,627, granted March 21, 1893.

The squeeze-rolls may be operated by a belt on a pulley 1), fast on the shaft of the lower squeeze-roll, the upper 'spueeze-roll being rotated by friction on said lower squeeze-roll or on the cloth E, passing between said squeezerolls, the submerging-rolls and carrier-roll being operated by the friction of the cloth thereon.

The tank may be divided by vertical partitions a (one such partition being shown) into two or more smaller tanks, through which the cloth passes successively, as described in said patent.

The cloth Eis represented as passing to the right in Figs. 2 and 3, from the carrier-roll to 5 5 the squeeze-rolls, being thus guided by the second spiral guides G, hereinafter described. The cloth after leaving the carrier-roll runs with its front edgethat is, theright edge in Figs. 2 and 3against the first or finger guides F, which are long curved metallic fingers, nearly crescent-shaped in horizontal crosssection, as'shown in Fig. 6, where the finger F at the left is shown in horizontal crosssection.

The finger may be straight, but must in that case be inclined in such a manner as'to depress the front or leading edge of the string of cloth, which is bunched or doubled laterally in the usual manner. The amount of depression of the leading edge of the string of cloth will obviously depend to a great extent on the pressure of the fingers F against said cloth, and said fingers F are therefore rigidly secured on an adjustable horizontal finger-bar f, which is longer thanthe tank A and slides in the supporting-plates H H, Figs.

1, 4, and 6, and is moved endwise by a screw 1, which turns without advancing in a journal bearing or box J, bolted at j to the under side of said finger-bar, and engages a nut or threaded hole in the plate H, said screw being prevented from longitudinal movement in said box J by a collar 2 on said screw at one side of said box and by the hub 72 of the crank 8 5 i secured to said screw on the other side of said box. By turning said crank '5 the press ure of the fingers F against the cloth may be regulated as desired. The following edge of the string of cloth is raised by the pressure 0 thereon of the second guides G or spiral guides, each spiral guide having an attachingplateg, secured by bolts g, Figs. 3 and 7, to

'a rectangular guide-frame G, which extends over the tank A and is supported on swinging 5 arms 9 pivoted at g to the support-plates H H, the cloth passing through said frame G. The arms 9 may be swung toward or away from the squeeze-rolls to increase or diminish the pressure of the guides G on the cloth, and

when the proper pressure is obtained said arms are secured from movement by bindingscrews which pass through arc-shaped slots g concentric with the pivots g and enter threaded holes in said plates II II in an obvious manner, each guide having a tongue g, the lower or rear edge 9 of which is a spiral which rises and advances in the general direction in which the cloth movesthat is, to the right in Fig. 3said tongue near its free end g descending below the string of cloth to prevent the disengagement of the cloth from said guide Gr.

The arms g carry a rod K, which prevents the cloth from getting below the nose g or free rear ends of each guide G and being torn thereby, said rod K extending horizontally under all of said guides and having its upper surface slightly above the free ends of the same.

The effect of the guides F G is to turn the.

laterally-gathered string or ribbon of cloth E about its axis ninety degrees, or preferably something more than ninety degrees, (because the cloth after leaving the spiral guide G has a tendency to turn back,) just before each entrance of the cloth between the squeezerolls, in order that the pressure of said rolls may flatten the edges of said string and make new edges and thus subject every part of the cloth to pressure while the same is passing through the machine, the greatest pressure of said rolls usually falling on the middle of the string of cloth, while the edges of the string,

being thinner, are not squeezed sufficiently" to extract the water or other liquid absorbed by the cloth from the tank.

\Vhen the cloth is again drawn through the liquid in the tank, said cloth partly opens, especially between the submerging-rolls, and every part of the cloth thus becomes equally acted upon by the liquid. The cloth, after its last immersion, passes through the guide G or hole in the guide-frame G, which is arranged in such a manner as to be superimposed upon the last preceding turn of the cloth to increase the pressure of the squeezerolls upon said last turn and to cause the cloth to emerge from the machine more nearly dry.

I claim as my invention- 1. The combination of a tank, a pair of squeeze-rolls, guides arranged to depress the leading edge of a string of cloth about to enter.

between said rolls, a sliding bar, upon which said guides are rigidly secured, to vary the pressure of said guides upon said cloth and other guides, to raise the following edge of said string, as and for the purpose specified.

2. The combination of a tank, a pair of squeeze-rolls, guides arranged to depress the leading edge of a string of cloth about to enter between said rolls, a sliding bar, upon which said guides are rigidly secured, a journal box, secured to said bar, a support for said bar, a screw, turning without advancing in said box, and engaging a threaded hole in one of said plates,to vary the pressure of said guides upon said cloth, and other guides, to raise the following edge of said string, as and for the purpose specified.

3. The combination of a tank, a pair of squeeze rolls, guides arranged to depress the leading edge of a string of cloth about to enter between saidrolls, stationary supports, arms pivoted on said supports, aframe, carried by said arms, and other guides, secured on said frame and adaptedto raise the following edge of said string to vary the pressure of said last named guides upon said string, as and for the purpose specified.

4. The combination of a tank, a pa1r of squeeze-rolls, guides, arranged to depress the leading edge of a string of cloth about to enter between said rolls, stationary supports, arms pivoted on said supports, aframe, carried by saidarms, and other guides, secured on said frame and adapted toraise the following edge of said string, said arms having arc-shaped slots, concentric with the pivots of said arms, and binding screws, which passthrough said slots into said stationary supports, to vary the pressure of said last named guides upon said string, as and for the purpose specified.

5. The combination of the squeeze-rolls, a guide, to depress the leading edge of a string of cloth, and another guide having a tongue provided with a spiral rear edge which advances in the general direction in which the cloth moves, to allow the saiddepressed edge of said string to escape from said last-na1ned guide, as and for the purpose specified.

6. The combination of a tank, a pair of squeeze-rolls, guides or fingers, arranged to depress the leading edge of a string of, cloth aboutto enter between said rolls, other spiral guides, to raise the following edge of said string, and a supporting-rod,to hold the string of cloth above the free endsof said spiral guides and to prevent said cloth from being caught on said free ends of said guides. and being torn thereby, as and for the purpose specified.

In witness whereof I havesigned thisspecification, in the presence of two attesting witnesses, this 26th day of October, A. D. 1894.
